HTC Touch Freezing from IMAP?

[thegreatpjdj]

So, I've had this issue for a while - can't really find any answer. My girlfriend and I both have Touchs. I got mine used, her's is new. Flashed them both with the latest ROM from Sprint. Without installing anything else, I added my Gmail account via IMAP and set it to check my mail every 5 minutes. I then noticed my phone would freeze randomly, so I thought I had a bum phone. I sold off mine and got a refurbished one. Again, same problem. I changed the mail checker to manual and I noticed that maybe 6/10 times there was no problem, but roughly 4/10 times the phone would get sluggish for a few minutes and eventually freeze. This doesn't seem to happen to my other IMAP clients - just gMail.

Any ideas?

Thanks guys!
